| Package Gross Weight | 20.000kg | | Raw Material Selection | We source high-quality 304 (A2) stainless steel wire with verified chemical composition and mechanical properties, ensuring the base material meets or exceeds ASTM, DIN, and ISO standards for corrosion resistance and tensile strength. | | Cold Heading & Forming | The screw blanks are formed via precision cold heading to create the pan head and unthreaded shank, ensuring a seamless, high-strength structure without material stress or defects. | | Thread Rolling | High-precision thread rolling is used to form uniform, burr-free machine threads on the shank, creating a consistent half-thread profile that delivers reliable engagement and torque performance. | | Precision Machining (Optional) | For custom lengths or special tolerances, we perform secondary CNC machining to ensure exact dimensional accuracy for specialized applications. | | Surface Finishing & Passivation | The screws undergo a strict passivation treatment to enhance the natural corrosion resistance of 304 stainless steel, followed by a polished finish for a smooth, hygienic surface free of burrs and contaminants. | | Customization & Packaging | We offer full customization for thread size, length, material grade (316 stainless steel optional), and packaging, with flexible options (standard export cartons, pallets, custom branding) to meet global logistics and OEM requirements. | | Exceptional Corrosion & Rust Resistance | Made from premium 304 (A2) stainless steel, these screws offer superior resistance to rust, oxidation, and mild chemical exposure, ensuring long-term reliability in marine, outdoor, food processing, and hygienic environments. | | Optimized Half-Thread Design | The smooth, unthreaded shank allows for precise clamping, alignment, and load distribution, preventing thread damage to workpieces and ensuring a tight, secure fit in through-hole applications. | | Universal Phillips Drive for Easy Installation | The standard cross recess is compatible with all common screwdrivers and power tools, enabling quick, consistent installation and reduced cam-out risk, boosting efficiency in high-volume production lines. | | Versatile Pan Head Profile | The low-profile, rounded pan head sits flush or slightly above the workpiece surface, making it ideal for applications with limited clearance and ensuring a clean, professional finish. | | High Strength & Durability | 304 stainless steel provides excellent tensile strength, hardness, and fatigue resistance, making these screws suitable for heavy-duty industrial, construction, and automotive applications. | | Hygienic & Food-Safe | The passivated, smooth stainless steel surface is non-toxic, easy to clean, and resistant to bacterial growth, making it ideal for food processing, medical equipment, and pharmaceutical applications. | | Cost-Effective & Customizable Solution | We offer competitive pricing for bulk orders, flexible MOQs, and full customization capabilities (size, material, length) to meet the unique requirements of any project, from small-batch OEM to large-scale industrial procurement. | | Rigorous Quality Assurance | Every screw is manufactured and inspected to international standards (DIN 7985, ISO 7045, ANSI B18.6.3), with material test reports (MTRs) and certifications available upon request, ensuring reliable performance and peace of mind for global buyers. | | Marine & Offshore Equipment | Securing boat hardware, deck fittings, and marine components exposed to saltwater and harsh coastal environments | | Food & Beverage Processing | Fastening food processing machinery, kitchen equipment, and sanitary installations, thanks to food-safe, hygienic stainless steel | | Medical & Pharmaceutical Devices | Mounting medical equipment, lab instruments, and pharmaceutical production machinery, where corrosion resistance and hygiene are critical | | Outdoor & Architectural Hardware | Securing outdoor furniture, building facades, window frames, and solar panel installations, with excellent weather and UV resistance | | Automotive & Transportation | Fastening interior/exterior components, electrical systems, and vehicle accessories, especially in corrosion-prone environments | | Electronics & Electrical Equipment | Mounting circuit boards, enclosures, and power distribution hardware in industrial and commercial electrical systems | | Industrial Machinery & Equipment | Assembling production machinery, conveyor systems, and industrial tools, where precise clamping and alignment are required | | Furniture & Cabinetry | Securing hardware, brackets, and assemblies in commercial and residential furniture, with a clean, professional finish | | Renewable Energy Systems | Mounting solar panels, wind turbine components, and energy storage systems, ensuring long-term reliability in outdoor environments | | Quality Assurance | All products undergo rigorous testing and inspection to ensure compliance with international standards. | | Competitive Pricing | Our advanced manufacturing processes allow us to provide high-quality products at competitive prices. | | Timely Delivery | With a large production capacity and efficient supply chain, we guarantee on-time delivery to meet your project deadlines. | | Category | [Button, Pan & Round-Head
